Jennifer Garner and Ben Affleck spend their Sunday morning (August 17) together running some errands at a gas station in Brentwood, Calif.

Recently, Ben‘s Gone Girl director David Fincher explained casting the role of Nick.

“We knew we needed somebody who was charming and could be seductive, who could be a ladies man, a guy’s guy, a frat boy,” David told Entertainment Weekly. “But most important, [someone] who had the wits and experience of knowing that situation. The gift of having Ben Affleck is that this is a guy who knows. He knows what a lose-lose situation is and understands what’s funny about it, however sad.”
